Web Services Interoperability Technology (WSIT) is an open-source project started by Sun Microsystems to develop the next-generation of Web service technologies. It provides interoperability between Java Web Services and Microsoft's Windows Communication Foundation (WCF).

It consists of Java programming language APIs that enable advanced WS-* features to be used in a way that is compatible with Microsoft's Windows Communication Foundation as used by .NET. The interoperability between different products is accomplished by implementing a number of Web Services specifications, like JAX-WS that provides interoperability between Java Web Services and Microsoft Windows Communication Foundation.

WSIT is currently under development as part of Eclipse Metro.

WSIT is a series of extensions to the basic SOAP protocol, and so uses JAX-WS and JAXB. It is not a new protocol such as the binary DCOM.

WSIT implements the WS-I specifications, including:

• WS-MetadataExchange

• WS-Transfer

• WS-Policy

Security

• WS-Security

• WS-SecureConversation

• WS-Trust
